ALLOY.

Ito Drawing.

To all whom it may concern Be it known that I, VICTOR -PEREZ TAYLOR, a citizen of'MeXico, and a resident of the cityv of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Alloy, of which the following is a full, clear, and exact description.

This invention relates to a metal compound, and aims to provide a product which will combine practically the lightness of aluminum with the strength of extremely hard metals.

It is well known that the great disadvans tage in connection with aluminum is that it is frangible, and that once broken it is dificult to weld or solder it together. lln view of the foregoing, structures made of aluminum, such as airplane struts, flying-machine framework, and other applications to which metal is adapted, which metal must combine extreme lightness,-have been prohibitive in cost, in View of the fact that when once broken it has 'been diflicult to repair any part and an-entire new part had to be made.

It has been impossible, on the other hand,

' to eliminate this expense by utilizing iron,

steel, etc., in .view of the great weight incident to the usage of these materials. In

View of the foregoing, I have, as outlined above, produced a metal which will combine practically the strength of extremely hard metals, in addition to the fact that my metal may be easily molded, joined, bent, adjusted and.

. soldered.

A further and great advantage of the metal compound hereinafter set forth is that the same is not brittle and may, accordingly, be subjected to any number of sudden strains or blows without any danger of breakage.

To produce metal combining the qualities aforementioned, I take a crucible, of any desirable size, in which the following material .is placed; aluminum and copper to which is added a a small uantity of a flux such as glass powder. J his mixture is brought to a melting temperature, and when in a goodfluidvstate, small compound such an oxidizing agent such as potassium bis chromate are added, and later finely granulated cast iron.

A short time after quantities of a, tungsten the addition of the iron, the slag is removed and; the fluid metal is poured out into molds. I

the lightness of aluminum with and after standing, as sodium tungstate and- Specification of Letters Patent. P t t fq 24, 1920.

Application filed August 4, 1919. Serial No. 315,174.

The proportions in which the above ma terials are utilized are preferably as follows:

quantities of sodium tungstate, in the proportion of 47 .50 parts; potassium bichromate, 12 parts; and finely granulated cast iron, l5.parts, are added.

After the scum has been removed and the metal poured and cooled, it will be found that l. have produced a metal combining a mechanical resistance of ten per cent. less than that of iron; and a metal which may be very easily molded, cut, welded, soldered, etc.

The specific weight of this metal is slightly higher than that of aluminum, but, on the other hand, it willreadily be appreciated that the difference in Weight of these two metals is not so perceptible that my metal may not be adapted to every use to which aluminum is placed at the present time.

It will be found that the melting point, of the metal produced by the foregoing mire ture of materials is between 1050 and 1350 centigrade. j

@bviously, certain modifications in the proportions .of materials employed may be resorted to without in the slightest departin from the scope of my invention.

aving thus described my invention, I desire to claim:

1. An alloy containing aluminum 80 to 100 parts, copper 8 to 17 parts, and tungsten.

2. A process for making an alloy which consists in melting aluminum and copper in the presenceof a slagging material, adding a tungsten compound, an oxidizing agent, and after standing, adding finely divided iron, and removing the slag.

8. A process for making an alloy which consists in melting aluminum and copper in the presence of a slagging material, adding sodium tungstate and an oxidizing agent, adding finely divided iron, and removing the slag.

4:. A process for making an alloy which consists in melting aluminum and copper in the presence of a slagging material, adding a tungsten compound -and potassium b1- chromate, and after standing, adding finely 5. A process for making an alloy which consists in melting aluminum and copper in the presence of a slagging material, adding sodium tungstate and potassium bichromate, and after standing, adding finely divided iron, and removing the slag.

6. A process for making an alloy which consists in melting aluminum and copper in the presence of glass, adding sodium tungstate and potassium bichromate, and after standing, adding finely divided'iron, and removing the slag.

.7. A process for making an alloy which 'ing finely with 13 parts of copper in the presence of glass, adding tungstate 47%-.parts, potassium dichromate 12 parts, and after standing add- P nd remov divided iron 15 ing the slag.

8., An alloy containing aluminum 190 parts, copper 13 parts, and tungsten. 9 alloy containing aluminum 100 parts, copper 13 parts, and tungsten prepared substantially as described.
